본 발명은 헤더파이프(header pipe)에 대한 납땜불량을 저감하도록 한 열교환기용 튜우브와 각종 길이의 튜우브를 합리적으로 제작할 수 있도록 한 열교환기용 튜우브의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat exchanger tube and a method for manufacturing a heat exchanger tube that can be reasonably manufactured in various lengths of tubes for reducing soldering defects in a header pipe.
종래, 이러한 종류의 튜우브속에 알루미늄을 압출성형한 것이나 일본국 실개평 2-28980호 공보와 같이 편평관에 이너핀(inner fin)을 삽입한 것이 있었다.Conventionally, aluminum was extruded into a tube of this kind, or an inner fin was inserted into a flat tube as in Japanese Patent Application Laid-Open No. 2-28980.
그러나, 이것들은 성형이 어렵고, 더욱이 튜우브내의 각 통로가 완전히 분할되어 있기 때문에 열교환 유체의 교반작용을 얻을 수 없고 열교환 효율이 일반적으로 낮다고 하는 문제가 있었다.However, these are difficult to mold, and furthermore, since each passage in the tub is completely divided, there is a problem that the stirring action of the heat exchange fluid cannot be obtained and the heat exchange efficiency is generally low.
이 때문에 상기와 같은 문제를 개선한 것으로서, 예컨대 일본국 특개평 3-155422호 공보에는 길죽한 판재를 로올성형(roll forming)하여 두겹으로 접어굽으리고 그 끝 가장자리를 납땜함과 동시에 그 내면에 다수의 돌기를 설치하여 돌기를 대향배치하는 한편, 그것들 사이에 열교환 유체를 도입한 다음 이 유체를 교반하고 열교환 효율을 높이도록 한 열교환기용 튜우브와 그 제조방법이 개재되어 있다.For this reason, the above-mentioned problems have been improved. For example, Japanese Patent Laid-Open No. 3-155422 discloses a rolled sheet of rolled sheet, which is folded in two layers and solders its edges to the inner surface of the sheet. There is provided a heat exchanger tube and a manufacturing method thereof in which protrusions of the heat exchanger are arranged to face the protrusions, a heat exchange fluid is introduced therebetween, and then the fluid is stirred and the heat exchange efficiency is increased.
그러나, 상기한 열교환기용 튜우브는 열교환 효율을 향상할 수 있는 반면에 헤더파이프(header pipe)에 납땜하는 경우, 상술한 돌기가 납땜부분에 위치하면 돌기에 대응하는 요부와 튜우브 삽입구멍 내면과의 사이에 납땜의 테어링(tearing)이 발생하여 그부분이 납땜불량을 일으킨다고 하는 문제가 있었다.However, while the above-described heat exchanger tube can improve heat exchange efficiency, when soldering to a header pipe, when the above-described projection is located at the soldered portion, the groove corresponding to the projection and the inner surface of the tube insertion hole are formed. There was a problem that tearing occurred during soldering, and that part caused solder failure.
본 발명의 목적은 이와 같은 문제를 해결하여 헤더파이프와 튜우브의 납땜 불량을 저감할 수 있는 열교환기용 튜우브를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a heat exchanger tube that can solve such a problem and reduce the soldering failure of the header pipe and the tube.
본 발명의 다른 목적은 튜우브의 여러가지 길이에 따라 튜우브 성형부재의 절단위치를 용이하게 또한 합리적으로 설정할 수 있는 열교환기용 튜우브를 제공함에 있다.Another object of the present invention is to provide a tube for a heat exchanger that can easily and reasonably set the cutting position of the tube forming member according to various lengths of the tube.
본 발명의 또 다른 목적은 헤더파이프와 튜우브의 납땜불량을 저감할 수 있는 열교환기용 튜우브의 제조방법을 제공함에 있다.It is still another object of the present invention to provide a method for manufacturing a heat exchanger tube that can reduce soldering defects of a header pipe and a tube.
본 발명의 다른 목적은 튜우브의 여러 가지 길이에 따라서 튜우브 성형부재의 절단위치를 용이하게 또한 합리적으로 설정할 수 있는 열교환기용 튜우브의 제조 방법을 제공함에 있다.Another object of the present invention is to provide a method for manufacturing a heat exchanger tube that can easily and reasonably set the cutting position of the tube forming member according to various lengths of the tube.
이 때문에 본 발명의 열교환기용 튜우브의 헤더파이프에 튜우브 삽입구멍을 형성하고, 이 구멍에 납재료를 피복한 튜우브의 단부를 삽입하여, 이 튜우브를 튜우브 삽입구멍에 납땜함과 동시에 튜우브의 내부에 이 튜우브재료를 안쪽으로 돌출시킨 여러개의 돌기를 설치한 열교환기용 튜우브에 있어서, 튜우브의 양단부에서 적어도 튜우브의 삽입구멍의 대응위치에 평탄부를 설치하므로서 튜우브와 튜우브 삽입구멍 사이에 있어서의 납땜의 테어링의 발생을 방지하여 그것들의 납땜불량을 방지하도록 한 것을 특징으로 한다.For this reason, a tube insertion hole is formed in the header pipe of the heat exchanger tube of the present invention, the end of the tube coated with lead material is inserted in the hole, and the tube is soldered to the tube insertion hole. In a heat exchanger tube having a plurality of projections in which the tubing material is projected inward, the tubing and the tubing are provided at least at the corresponding positions of the insertion holes of the tubing at both ends of the tubing. It is characterized by preventing the occurrence of soldering tearing between the insertion holes and preventing their soldering defects.
또, 본 발명의 열교환기용 튜우브의 제조방법은 상대하는 알류미늄 납땜시이트(brazing sheet)에 여러개의 돌기를 성형하고, 이 시이트를 튜우브의 일정길이로 절단하여 돌기를 서로 맞대어서 납땜함과 동시에 상기 시이트의 양측단부를 납땜하도록 한 열교호나기용 튜우의 제조방법에 있어서, 상기 시이트의 길이방향으로 여러개의 돌기와 일정 면적의 평탄부를 번갈아 성형하여 평탄부 또는 그 근접위치에서 시이트를 절단함에 따라 튜우브의 각종 치수에 대응하는 시이트의 절단위치를 용이하게 또한 합리적으로 설정할 수 있음을 특징으로 한다In addition, in the method for manufacturing a heat exchanger tubing of the present invention, a plurality of protrusions are formed on a corresponding aluminum brazing sheet, and the sheet is cut to a certain length of the tube to solder the protrusions to each other. In the method of manufacturing a heat exchanger tub for soldering both ends of the sheet, a plurality of protrusions and a flat portion of a predetermined area are alternately formed in the longitudinal direction of the sheet to cut the sheet at the flat portion or its adjacent position. It is characterized in that the cutting position of the sheet corresponding to various dimensions of the sheet can be easily and reasonably set.
튜우브의 양단부에서 적어도 튜우브 삽입구멍의 대응위치에 평탄부를 설치하여 튜우브의 튜우브 삽입구멍 사이에 있어서의 납땜의 테어링을 방지하여 그것들의 납땜불량을 방지한다.A flat portion is provided at least at the corresponding positions of the tube insertion holes at both ends of the tube to prevent the soldering of the solder between the tube insertion holes of the tube and preventing their soldering defects.
시이트의 길이방향으로 여러개의 돌기와 일정면적의 평탄부를 번갈아 성형하고 평탄부 또는 그 근접위치에서 시이트를 절단하므로서 튜우브의 각종 치수에 대응하는 시이트의 절단위치를 용이하게 또한 합리적으로 설정할 수 있다.It is possible to easily and reasonably set the cutting position of the sheet corresponding to various dimensions of the tubing by alternately shaping a plurality of projections and a flat portion having a predetermined area in the longitudinal direction of the sheet and cutting the sheet at the flat portion or its vicinity.

더욱이, 튜우브(4)의 전영역에 걸쳐서 난류형성부(11)를 형성하므로서, 열교환유체의 교반작용을 높이고, 열교환 효율을 향상하도록한 점을 특징으로 하고 있다.Further, the turbulence forming portion 11 is formed over the entire area of the tub 4, thereby enhancing the stirring action of the heat exchange fluid and improving the heat exchange efficiency.
제10도 및 제11도에 나타낸 실시예는 튜우브(4)의 한쪽면, 즉 내면일대에 미소돌기(18)를 연속하여 그물코형상으로 가압성형하고, 난류형성부(11)의 작용을 증진시킴과 동시에 유퉁브(4)의 바깥면에는 미소돌기(18)에 대응하는 오목부의 형성을 저지하고, 소정위치에서의 평탄부(10)의 형성을 확보하고 있다.10 and 11, the micro-projections 18 are continuously press-molded in a mesh shape on one side of the tube 4, i.e., the inner surface, and the action of the turbulence forming section 11 is enhanced. At the same time, the outer surface of the groove 4 is prevented from forming a recess corresponding to the micro projections 18, and the formation of the flat portion 10 at a predetermined position is ensured.
그리고, 미소돌기(18)의 성형후, 전술한 실시예와 마찬기지로 돌기(12)를 성형하고, 접합부(13,13)와 절곡부(14)를 성형하여 절곡부품(4a,4b)을 두겹으로 절곡하도록 하고 있다.After the shaping of the micro projections 18, the projections 12 are formed in the same manner as in the above-described embodiment, and the joining portions 13 and 13 and the bent portions 14 are formed to form the bent parts 4a and 4b. It is trying to bend twice.
이러한 경우, 미소돌기(18)는 상기와 같은 리브형상의 것에 한정하지 않고 산점(散点)형상으로 형성하여도 좋다.In such a case, the fine protrusions 18 may be formed in a scattered shape, without being limited to the above rib-like ones.
더욱이, 전술한 실시예는 어느 것이나 로울성형에 의하여 튜우브(4)를 성형하고 있으나, 이것을 프레스 성형으로 하는 것도 가능하고, 또 난류형성부(11)는 도시한 바와 같은 원통형의 돌기(12)에 한정하지 않고 원추대나 타원형이였어도 좋고, 또한 그것들의 돌기(12)의 높이를 획일적으로 형성하는 대신에 일부의 높이를 낮게 형성하는 것도 가능하다.In addition, in the above-described embodiment, all of the tubing 4 is formed by roll forming, but it is also possible to press-form this, and the turbulence forming unit 11 has a cylindrical projection 12 as shown. The shape may be a truncated cone or an ellipse, and instead of uniformly forming the heights of the projections 12, some heights may be formed low.
이와 같이 구성한 열교환기용 튜유브를 제조하는 경우는 예컨대 튜우브(4)의 블랭크 상당폭의 알루미늄 납땜시이트를 리일(도면에 없음)에 코일형상으로 돌려감아서 이것을 성형로울(도면에 없음)에 공급한다.In the case of manufacturing the tubular for heat exchanger configured as described above, for example, a blank aluminum brazing sheet of the tub 4 is wound in a coil shape to a rail (not shown) and supplied to a forming roll (not shown). do.
이와 같이하면 알루미늄 납땜시이트가 제5도와 같이 길이방향으로 절곡되고, 절곡부품(4a,4b)과 접합부(13,13)가 절곡부(14)를 중심으로 대칭으로 성형되어 있다.In this way, the aluminum solder sheet is bent in the longitudinal direction as shown in FIG. 5, and the bent parts 4a and 4b and the joining portions 13 and 13 are formed symmetrically about the bent portion 14.
또 절곡부품(4a,4b)에는 여러개의 돌기(12)와 평탄부(10)가 연속적으로 또한 번갈아 성형되었고, 또한 그것들은 절곡부(14)를 중심으로 대칭으로 성형되어 있다.Moreover, several protrusions 12 and the flat part 10 were shape | molded continuously and alternately in the bent parts 4a and 4b, and they are formed symmetrically about the bent part 14, respectively.
상기를 성형한 다음 알류미늄 납땜시이트를 성형로울에 인접하여 설치한 벤딩머신인(도면에 없음)에 이송하여, 이 성형기로 절곡부(14)를 중심으로 두겹으로 접어굽으려 제3,4도와 같이 성형한다.After molding, the aluminum solder sheet is transferred to a bending machine (not shown) installed adjacent to the molding roll, and folded into two layers around the bent portion 14 by the molding machine as shown in FIGS. Mold.
그런 다음 성형튜우브(4)를 성형기에 인접하여 설치한 절단기에 이송하고, 이 절단기로 절단선(C1)을 경계로 평탄부(10)를 절단한다.Then, the molding tube 4 is transferred to a cutting machine provided adjacent to the molding machine, and the flat part 10 is cut by the cutting line with the cutting line C1 as a boundary.
이렇게 하여 일정길이로 절단된 성형튜우브(4)는 절곡부품(4a,4b)의 양단면 바깥면에 평탄부(10,10)가 위치하였고, 그것들 사이의 절곡부품(4a,4b)의 내면에 다수의 돌기(12) 집단으로 된 난류형성부(11)가 설치되었으며, 이것들 평탄부(10)와 난류형성부(11)는 튜우브(4)의 길이방향의 중앙을 중심으로 좌우대칭되게 배치되어 있다.In this way, the formed tubing 4 cut to a predetermined length has flat portions 10 and 10 positioned on the outer surfaces of both end surfaces of the bent parts 4a and 4b, and the inner surfaces of the bent parts 4a and 4b therebetween. The turbulence forming part 11 of the group of protrusions 12 was installed in these, and the flat part 10 and the turbulence forming part 11 are symmetrically centered about the center of the tube 4 in the longitudinal direction. It is arranged.
성형튜우브(4)의 면에는 제3도와 같이 돌기(12)의 대응위치에 오목구멍(17)이 형성되었고, 또 이 튜우브(4)의 안쪽에서는 돌기(12,12)가 제4도와 같이 맞대었고 또 접합부(13,13)가 상대(相對)하여 내면을 중합시키고 있다.On the surface of the forming tube 4, a concave hole 17 is formed at a corresponding position of the projection 12, as shown in FIG. 3, and inside the tube 4, the projections 12, 12 are formed at the fourth degree. Butt joints 13 and 13 are opposed to each other to polymerize the inner surface.
제8~11도의 튜우브(4)도 대략 마찬가지로 성형된다.The tube 4 of FIGS. 8-11 is also shape | molded substantially similarly.
다음에 상기 성형안 다음의 튜우브(4)를 납땜하기전에 헤더파이프(2,3)에 조립하는 경우에는 우성 한쌍의 끝판(6)과 탱크 플레이트(7)를 준비하여 이것들을 서로 마주보게 하여 끼워맞춤과 동시에 일정위치에 분할판(15)을 부착하여 한쌍의 헤더파이프(2,3)를 조립한다.Next, in the case of assembling the header pipes 2 and 3 before soldering the tubing 4 following the forming method, a pair of dominant end plates 6 and a tank plate 7 are prepared to face each other. At the same time, the pair of header pipes 2 and 3 are assembled by attaching the divider plate 15 at a predetermined position.
그리고, 이것들 헤더파이프(2,3)의 끝판(6,6)에 형성한 튜우브 삽입구멍(9,9)에 성형한 다음의 튜우브(4)를 찔러 넣고, 이 튜우브(4,4)사이에 방열핀(5)을 배치한다.Then, the next tube 4 formed into the tube insertion holes 9 and 9 formed in the end plates 6 and 6 of the header pipes 2 and 3 is inserted into the tube 4 and 4. The heat dissipation fins 5 are arranged between the layers.
또, 헤더파이프(2,3)의 상하단부에 뚜껑(16)을 끼워넣고, 이것들을 클립 또는 적당한 공구로 일시고정한다. 이렇게 일시 고정한 열교환기(1)를 납땜로(爐)에 반입하여 로안에서 각 납땜부분을 일시에 납땜한다.Moreover, the lid 16 is inserted in the upper and lower ends of the header pipes 2 and 3, and these are temporarily fixed with a clip or a suitable tool. The heat exchanger 1 temporarily fixed in this way is brought into a soldering furnace, and each soldering part is soldered in the furnace at a time.
즉, 끝판(6)과 탱크 플레이트(7)는 그것들의 접합부(8,8)에서 납땜되고 또 튜우브(4)는 표면의 납재료에 의하여 튜우브 삽입구멍(9)의 개구부에 납땜되어 튜우브(4)의 내면의 납재료에 의하여 돌기(12)끼리 납땜됨과 동시에 접합부(13,13)가 내면의 납재료에 의하여 납땜된다.That is, the end plate 6 and the tank plate 7 are soldered at their joints 8 and 8, and the tubing 4 is soldered to the opening of the tubing insertion hole 9 by the lead material on the surface. The projections 12 are soldered to each other by the solder material on the inner surface of the web 4, and the joints 13 and 13 are soldered by the solder material on the inner surface.
이러한 경우, 튜우브 삽입구멍(9)의 개구부에는 튜우브(4)의 바깥면에 설치한 평탄부(10)가 위치하고 있기 때문에 그것들의 접합부가 밀접하여 용융납이 똑같이 분포하여 튜우브(4)의 바깥면과 튜우브의 삽입구멍(9)의 개구부와의 사이에 침입하여 그것들을 똑같이 납땜한다.In this case, since the flat part 10 provided on the outer surface of the tub 4 is located in the opening of the tubing insertion hole 9, the joints thereof are in close contact, and the molten lead is distributed in the same manner. It penetrates between the outer surface of and the opening of the insertion hole 9 of the tube, and solders them equally.
따라서 종래와 같이 튜우브 삽입구멍(9)의 개구부에 오목구멍(17)이 위치하므로서 당해 부분이 납땜 테어링을 일으켜 납땜불량으로 되는 상태를 방지할 수 있다.Therefore, since the concave hole 17 is located in the opening of the tube insertion hole 9 as in the related art, it is possible to prevent a state in which the portion causes solder tearing and leads to solder failure.
이러한 경우, 제1실시예에서는 튜우브 삽입구멍(9)의 개구부 주변에 넓은 평탄부(10)를 설치하고 있기 때문에, 용융납이 오목구멍(17)에 유입하여 체류하는 일이 없이 용융납의 똑같은 분포가 촉진되어 납땜불량을 강력하게 방지한다.In this case, in the first embodiment, since the wide flat portion 10 is provided around the opening of the tubing insertion hole 9, the molten lead does not flow into the concave hole 17 and stay there. The distribution is promoted to strongly prevent soldering defects.
한편, 제2실시예에서는 헤더파이프(2,3)내에도 난류형성부(11)를 설치하고 있기 때문에 열교환 유체의 교반작용을 증진시킴과 동시에 돌기(12)에 의한 강성이 증대하여 이부분의 강도가 강화되어 내압성능을 향상할 수 있다.On the other hand, in the second embodiment, since the turbulence forming portion 11 is also provided in the header pipes 2 and 3, the stirring action of the heat exchange fluid is enhanced, and the rigidity by the projections 12 is increased so that Strength can be enhanced to improve the pressure resistance performance.
또, 제10,11도에 나타낸 제3실시예에서는 미소돌기(18)에 의하여 난류형성부(11)에 의한 열교환 유체의 교반작용을 한층 촉진한다.In the third embodiment shown in Figs. 10 and 11, the stirring action of the heat exchange fluid by the turbulence forming section 11 is further promoted by the micro projections 18. Figs.
이와 같이 본 발명의 열교환기용 튜우브는 튜우브의 양단부 바깥면에서 적어도 튜우브 삽입구멍의 대응위치에 평탄부를 설치하였기 때문에 종래와 같이 튜우브 삽입구멍 주변에 납땜의 테어링을 오발하는 돌기와 일체의 오목구멍이 위치하는 염려가 없이 튜우브와 삽입구멍 내면과의 상이에 있어서의 납땜테어링을 방지하여 그것들의 납땜불량을 방지할 수 있다.Thus, since the tubing for heat exchanger of the present invention is provided with a flat portion at least at the corresponding position of the tube insertion hole on the outer surface of both ends of the tube, it is integral with the projection which misleads the tearing of solder around the tube insertion hole as in the prior art. It is possible to prevent solder soldering at the difference between the tub and the inner surface of the insertion hole without fear of the position of the recessed holes, thereby preventing their soldering defects.
또 본 발명의 열교환기용 튜우브의 제조방법은 시이트의 길이방향으로 여러개의 돌기와 일정 면적의 평탄부를 번갈아 성형하고 평탄부 또는 그 근접위치에서 시이트를 절단하도록 하였기 때문에 튜우브의 각종 치수에 따라서 시이트의 절단 위치를 용이하게 또는 합리적으로 설정할 수 있다.In the method of manufacturing a heat exchanger tubing according to the present invention, since the projections are formed alternately in the longitudinal direction of the sheet and the flat portions of a predetermined area are cut and the sheet is cut at the flat portion or its adjacent position, The cutting position can be easily or reasonably set.
